The shown circuit detects wiring faults in the area of the emergency stop
switchgear and the supply line. A possible short circuit on the primary side of the
emergency stop switchgear (ground and DC +24 V) and a short circuit on the sec-
ondary side of the device or within the wiring leads either directly or with closed
contacts to a short circuit of the supply, whereby an upstream 24 V fuse trips.
In addition to the two applications shown here with an emergency stop switching
device, other sensors (such as door switches, etc.) can be used in the same way.
